Limited capacity for rapid acclimation to marine heatwaves in coastal invertebrates

Journal of Animal Ecology, EarlyView.
Across 10 coastal invertebrate species, we provide a rare multi‐species test of rapid acclimation to realistic marine heatwaves. Responses are consistently weak, revealing that short‐term plasticity cannot keep pace with warming and may lead to underestimated vulnerability in coastal ecosystems. Abstract Marine heatwaves are increasing in frequency and

Comparative Molecular Insights into Developmental and Behavioral Toxicity Induced by Octocrylene and Ethylhexyl Salicylate Exposure on Zebrafish

Integrative Zoology, EarlyView.
This study compared the ecological toxicity of organic ultraviolet filters, octocrylene (OC) and ethylhexyl salicylate (EHS), on zebrafish embryos and larvae. EHS exhibited higher acute toxicity, causing increased mortality, hypoactive behavior at 50 mg/L, and disruptions in lipid homeostasis, while OC primarily affected hypoxia response and ...

Early life history of the Korean seahorse, Hippocampus haema: Evidence for direct settlement and ontogenetic shifts in snout morphology

Journal of Fish Biology, EarlyView.
Abstract Early life‐history traits of seahorses are closely linked to juvenile survival, dispersal potential and the onset of substrate attachment; however, detailed stage‐resolved descriptions remain limited for many Hippocampus species. This study examined reproductive behaviour and early ontogenetic development of the Korean seahorse, Hippocampus ...

Integrated multitissue analysis reveals distinct oxidative stress responses during recovery from cold shock in the Amazonian fish Colossoma macropomum

Journal of Fish Biology, EarlyView.
Abstract Tambaqui (Colossoma macropomum) is a tropical fish widely cultivated in South America. The increasing demand for this species has heightened interest in its cultivation in subtropical regions with greater thermal variability, where cold shock may induce oxidative stress. This study evaluated the effects of cold shock and subsequent recovery on
